I did 3 separate volume calculations yesterday for the pool, spa, and the sun shelf. My total is approximately 7,200 gallons. That's probably generous given I measured before the plaster, to the bottom edge of the coping, and didn't deduct for the staircase and a bit taken from the corner of the sun shelf due to the location of the electrical service. The equipment was delivered and installed yesterday. I was going to ask for the Intelliflo pump instead of the Superflo pump, but the Intelliflo was delivered without me having to ask for it. If I understand correctly, the iChlor can turn on and off with the Intelliflo without having to have automation. However, I don't know anything about automation, and didn't think I was getting any. While the equipment was being unpacked and installed, I asked whether the swg would be added by next Saturday, or whether they would wait to install it 30 days after the start-up. One of the guys didn't seem to know we were going with an swg and said it was going to be a very tight fit to add one. The guy who seemed to be in charge said they might wait because the water could be hard on the swg during the first 30 days. He also said the builder was ordering a panel for me, the Easy Touch, I believe he mentioned. Does that mean we will have automation after all? He indicated we had to get one because of the swg. The iChlor comes in a 15k gallon size, and a 30k gallon size. With the Intellichlor, I could choose 15k gallons or 20k gallons. The house sleeps 12-14, but I know many tenants squeeze more people in. I don't know whether everyone staying in the house will be in the pool at the same time. I personally would choose to be on the beach, and might only use the spa in the evening. What would you pick? The 15k gallon iChlor, or would you choose the 20k gallon Intellichlor? I was given prices for the Intellichlor 15 and the Intellichlor 20, but I haven't heard back yet on the price for the iChlor 15. I know he has not installed an iChlor yet. He said only 10 percent of his builds have salt water, and they all have the Intellichlor 15 or the Intellichlor 20.
